EF0 tornado in Calhoun County, Alabama

National Weather Service meteorologists surveyed damage in southwest Calhoun County and determined that it was consistent with an EF0 tornado, with maximum winds near 75 mph. The tornado began near the intersection of Mitchellville Road and Mayfield Road, where damage consisted of several uprooted trees and snapped trunks.

The tornado continued northeast toward Mudd Street where the most severe damage occurred at two residences. Two homes also sustained minor roof damage. The tornado likely dissipated as it moved past Mudd Street as no other damage was observed downstream. There was also evidence of a weak TDS associated with this tornado from the KBMX radar.

A very dynamic and deepening low pressure system moved through the Ohio Valley states on November 29-30 with a trailing cold.

Instability increased dramatically the evening of the 29th as 60 plus surface dewpoints advected northward into Central Alabama. A QLCS developed ahead of the approaching cold front in addition to discrete thunderstorms.
